Financial Services New York 501–1,000 employees Founded 2018 Privately Held

Melio operates a multi-rail payment platform (ACH, wire, card, check, international) with embedded integrations into accounting software like Xero. The stack reveals a data-forward architecture—SQL, Python, Airflow, dbt, Snowflake, Databricks, Kinesis, Kafka—paired with a modern frontend (React, Vue, Angular) and serverless compute (Lambda), suggesting heavy investment in real-time payment processing pipelines and reconciliation at scale. Active hiring in data infrastructure (3 roles) and engineering (14 roles, mostly senior/lead) points to scaling payment reliability and API-driven partner integrations.
